We examined the minimization effects of a subjective sense of poverty by social networks for urban workers and the mediating effects. The purposes of this study are to draw up measures and provide implications in community health care by gender. The findings are as follows: First, differences in understanding a subjective sense of poverty have been generated by demographic socio-economic characteristics according to gender. Second, differences in perception of the subjective sense of poverty have been generated by types of social networks according to the gender. Third, differences in types of social networks have been generated by gender. Fourth, differences in mediating effects of the types of social networks influencing a subjective sense of poverty have been generated by gender. We provide effective methods in community health care by analyzing these examinations.

Background: Although cranial electrotherapy stimulation (CES) is reported to have positive effects on mental functions such as depression and sleep improvement, detailed studies regarding awakening, attention and concentration among brain waves reflecting brain activity are lacking. Objective: To examine the effects of cranial electrotherapy stimulation (CES) on various electroencephalograms (EEGs) reflecting brain activities. Design: Randomized controlled clinical trial (single blind) Methods: This study selected 30 healthy adult women in their 20s who volunteered for this experiment. A total of 30 subjects were randomly assigned to three groups (Sham group, 0.5 Hz CES group, and 100 Hz CES group). EEGs were measured before and after the single CES, and the results were compared and analyzed. Results: The relative theta, alpha, and gamma waves indicated no significant differences in the interaction effects between time and group. The relative fast alpha wave only showed significant differences in the interaction effects between time and group in P4. The relative slow beta wave only indicated statistically significant differences in the interaction effects between time and group in T3 and T4. The relative mid and fast beta waves showed statistically significant differences in the interaction effects between time and group in all areas. Conclusions: These results suggest that a CES of 0.5 Hz awakens consciousness and has a positive influence on brain activity, while a CES of 100 Hz has a positive influence on thinking activity accompanying mental load during concentrating on one subject.

Recently, Live-Virtual-Constructive (L-V-C) integrate training system has proposed as a solution for the problems such as limitation of training areas, increase of mission complexity, rise in oil prices. In order to integrate each training system into the one effectively, we should solve the issue about stress of pilots by the environmental differences between Live and Virtual simulation which could be occurred when each system is connected together. Although it was already examined in previous study that the psychological effects on pilots was occurred by the environmental differences between actual and simulated flights, the study did not include what the causal factors affecting psychological effects are. The aim of this study is to examine which environmental factors that cause pilots' psychological effects. This study analyzed the biochemical stress hormone, cortisol to measure the pilots' psychological effects and cortisol was measured using Enzyme-linked immunoassay (EIA). A total of 40 pilots participated in the experiment to compare the differences in pilots' cortisol response among live simulation, virtual simulation, and the virtual simulation applying three environmental factors (gravity force, noise, and equipment) respectively. As a result, there were significant differences in cortisol level when applied the gravity force and equipment factors to the virtual simulation, while there was no significant difference in the case of the noise factor. The results from this study can be used as a basis for the future research on how to make L-V system by providing minimum linkage errors and design the virtual simulator that can reduce the differences in the pilots' psychological effects.

This study aimed to investigate the roles of three health-oriented personal factors-health technology innovativeness (HTI), health consciousness (HC), and health information orientation (HIO)-in determining Koreans' perceptions about telemedicine. Based on an extended version of the technology acceptance model (TAM), two perceptual components-perceived usefulness (PU) and perceived ease of use (PEOU)-of telemedicine were considered for this investigation. Data from 699 usable surveys were analyzed using path analysis. The results from the path analysis indicated that while HTI and HC had no or limited effects on the PU and PEOU of telemedicine, the effects of HIO on those two perceptual components of telemedicine were statistically significant. Moreover, the results from the path analysis showed that there were significant regional differences in the effects of HTI and HC on the PU and PEOU of telemedicine. In general, these effects were greater among the metropolitan residents than they were among the rural residents.

Niveteen stimulus photographs varied in hue and color scheme of one clothing style of Korean dress worn by a female were used to explore the differences in perceptive effect of clothing cues(color, color scheme, structure) on impression formation and graduate students. The data were analyzed by factor analysis, factor score, ANOVA and Scheffe-test. Results indicate perceptive effects of clothing cues on impression formation are influenced by gender-differences and major-difference of perceivers. Significant gender differences were found in perception of clothing cues on impression effect. Interaction effects were found between clothing cues and gender. Significant major differences were found in perception of clothing cues on impression effect. Interaction effects were found between clothing cues and perceiver's major. Female perceivers and perceivers of major-ing in Liberal Arts reacted to clothing cues on impression formation with greater sensitivity than male perceivers and perceivers of majoring in Natural Sciences. Frequent interaction effects between gender and color of China (cool-warm color), between major difference and color scheme(related color harmony-contrasting color harmony) appeared on factors of impression effect. The influence of perceiver variables on their perception of clothing cues for impression effcet has important implications for gender difference and perceiver's maforing backgroung in a social situation.

Four science concepts were selected from high school earth science textbook to investigate the differences in students knowledges activated in laboratory and earth environmemtal contexts. Two items, one is for laboratory and the other for earth environmental contexts, were develped for each selected concept. Students' responses were analyzed in terms of 'Common Activated Knowledges' (CAK), 'Specific Activated Knowledges'(SAK) across students' cognitive frames, grades and sexes. As contextual differences of the problems increased, gender contributed more than other variables to the frequencies of activating CAK and SAK. Context effects were also reported across cognitive frames for CAK, but SAK became more avtivated when the contextual differences of the items become smaller. As a whole, students with laboratory cognitive frames showed more significant context effects than others. Students in 11th grade, with scientific frames and with earth science cognitive frames showed relatively small context effects. The results of the study showed that sciene concepts learned in a laboratory context are not usually transferred spontaneously to earth environmental contexts. Special instructional strategies should developed to overcome the context effects.

The purpose of this study is to evaluate the differences of visual effects by variations in the location and width of the waist band of one-piece dress. The stimuli are 24 samples: 8 variations of the location of the waist band and 3 variations of the width of the waist band. The data has been obtained from 50 fashion design majors. The data has analyzed by Factor Analysis, Anova, Scheffe's Test and the MCA method. The results of the study are as follows: According to the result of factor analysis of the visual effects based on the changes in the location and width of waist bands for one-piece dress, four factors were identified - verticality of whole-body, horizontality of upper-body, curves of lower-body and shape of breast. Whole-body verticality and upper-body horizontality were found to be the most important factor among them. In all of the four factors of the visual effects, significant differences were observed according to the location of the waist bands for one-piece dress. The visual effects were evaluated positively when the waist bands were positioned above the natural waist line and negatively when the waist bands were positioned below the natural waist line. In addition, significant differences were observed in the visual effects according to the width of waist bands when the waist bands were positioned above the natural waist line, and visual effects were better when the band width was 3.5cm and 4.5cm than the others. The interaction of the visual effect showed significant differences in horizontality of upper-body, curves of lower-body and shape of breast.

One objective in developing the next generation of wireless communication systems is to increase data rates and reliability. A promising way to achieve this is to combine multiple-input and multiple-output signal processing with a space-time coding scheme, which offers higher coding and diversity gains and improves the spectrum efficiency and reliability of a wireless communication system. It is noted, however, that time delay differences and phase differences among different channels increase symbol interference and degrade system performance. In this letter, we investigate phase differences and their effects on multiple-input and multiple-output systems, and propose a compensation algorithm for the Rayleigh fading model to minimize their effects.
